(High Lights by Technic, available here for £2.60.)
The highlighter itself is absolutely gorgeous. Benefit's formula is slightly thicker and more creamy than this one, but personally, I think High Lights gives a more shimmery effect, which suits me perfectly for Summer when we can get away with a little more sparkle! The product is also really build-able, so if you're looking for a stronger shimmer then it is really easy to achieve this. Unfortunately, the brush applicator from Technic isn't brilliant quality and the bristles are in very bad condition on mine in particular, so I use my pointed foundation brush from Real Techniques to apply it to the cupids bow, cheek and brow bones. It blends into the skin really well and leaves you with a gorgeously healthy, dewy glow when it catches the light. The texture is very delicate and doesn't feel at all greasy on the skin which it great. I find it doesn't have quite the same staying power as High Beam, however I wasn't really expecting that from such a cheap highlight. But despite any minor niggles, you really cannot go wrong with this product. At £2.60 on Amazon, this is my highlighter of the Summer and I really cannot recommend more!
